Profound thoughts. I think that we often let others into the corridor or anteroom, but there exists a chamber reserved only for a select few. I don't think it is wrong that we are this way. In the recent thread titled, 'I Love You', it was mentioned that we only have the capacity to allow a few to truly see us, and to devote the time and energy to shore up that connection and ensure its survival. I suppose the fear comes from wondering if who we've allowed into the 'corridor' is truly worth it (the 'what if' you mentioned rings true). What if we devote all of this time and energy into cultivating this connection, only to have it be taken from us? I don't wish to rob myself of the joy of connection, but I also want to be discerning enough to know who belongs in my inner sanctum and who should exist on the periphery of it. If I already fear losing them, then they have already been given intimate access. The fear is made stronger, but so is the bond. Sure, they don't belong to us, and it is their choice, but that is what makes it all the more beautiful when they choose us repeatedly.
As for becoming anything, that's true, but it isn't a bad thing. We are dynamic, and hopefully we can improve not despite our fears, but because of them. If
anything is certain, it is change.
This is one of my favorite songs on the topic...
